The invention relates to industrial and civil construction and can be used in the construction of roads, airfields, piers of bridges, high-voltage masts, chimneys, towers, tall buildings, foundations for various structures, as well as when page is load-carrying supporting structure in the form of a flexible multi-layer coating of ground areas for the rapid construction of roads and airfields, containing layers reinforced spatial or planar geogrid soil, flexible separating layer of high-strength geotextile between them, while the geogrid is shifted one relative to the other and fastened to each other vertically flexible connections with the formation of closed cells, the separation layer is pre-strained and canvas upper supporting layer is made of waterproof fabric, and each section of the geogrid is a flexible module, consisting of bonded linear joints flexible plates convexo-concave shape (RU # 2044813, CL E 01 5/00, 27.09.95).

However, this design despite certain advantages has limited its use and significantly MATERIALICA.

Known load-carrying supporting structure containing plate, abutment surfaces of which are hooks in the form of ridges and convex-curved in plan anchor element is inclined in the transverse direction from the center of the base plate to its periphery side surface and having a closed arcuate sections projecting beyond the contour of the base plate by a value not less than the thickness of the ledge (RU # 2107768, CL E 02 D 27/02, 27.03.98).

Adnatest its execution.

Known supporting structure that contains the basis of thin-walled elements and the reference floor (FR No. 2728597, CL E 02 D 27/26, 28.06.96).

However, this load-carrying supporting structure significantly MATERIALICA.

Most similar in its essence and the achieved technical result is a bearing supporting structure that contains the basis of thin-walled elements and the supporting floor, and the elements of the base is produced convexo-concave in the longitudinal direction and are arranged at an angle to the vertical plane (see EN 2032790 C1, 10.04.1995, E 02 D 27/02).

Declared support structure is devoid of the above disadvantages and the most industrially applicable in operation due to high bearing capacity and stability of the spatial position in static and dynamic state irrespective of the magnitude of the vertical active and reactive forces and heave and horizontal forces offset.

The solution to this technical problem is achieved in that the bearing support structure containing the basis of thin-walled elements and the supporting floor, and the elements of the base is produced convexo-concave in the longitudinal direction and are located n aparecem direction.

In addition, when the device is rectangular in plan structures thin-walled elements can form a cellular system with diverging and converging downwards elements in cells.

The invention is illustrated by drawings, where

in Fig.1 shows a General view of the carrier support structure;

in Fig.2 - convex-concave base of the bearing supporting structure made in the form of a cellular system;

in Fig.3 - the same, in the form of a spiral;

in Fig.4 - the same, with diametrically oppositely located at the same distance from the center, respectively, convex and concave elements base;

in Fig.5 - same as pachycheilus system with a single cell in the center and four at the same distance from center to outer side;

in Fig.6 - the same, in the form of three equidistant ellipsoidal petals;

in Fig.7 depicts a convexo-concave basis in axonometry. Load-carrying supporting structure of the Foundation comprises a base 1 made of thin-walled elements 2 and the anchor coating 3. Thin-walled elements 2 of the base 1 is made convex-concave in longitudinal and transverse directions and are arranged at an angle to the vertical plane. volumes with diverging and converging towards the bottom of the cells 4 of thin-walled elements 2. Convexo-concave base 1 can be made in individual cases, depending on the construction, in the form of a coil 5 is tilted in the transverse direction of the side surface diverging slope from bottom to top.

When applying Foundation television and radio masts, towers and high-voltage power lines, chimneys and towers, high-rise buildings convexo-concave base 1 is made with diametrically oppositely located at the same distance from the centre (of a circle), respectively, convex 6 and concave 7 elements, and the elements 6 and the elements 7 are arranged on mutually perpendicular diameters and with the growing inclination of the lower part of the thin-walled elements, i.e. in the direction of removal of the centre of the base.

For the construction of the foundations of the tower, building or mast convexo-concave base 1 made in the form of pythiaceae system with the Central cell 8 and four outer cells 9 arranged at the same distance from the centre of the base.

To increase the holding torque from tipping over high towers, buildings or masts convexo-concave base is made in the plan in the form of three equidistant ellipsoidal petals 10, converging who s raising 1 thin-walled elements 2 (depending on soil) or set method indentation in the soil with subsequent backfilling of the Foundation soil, or pre-tear trench, set in her thin features grounds, covered the ground inside and outside the ground and fasten up the supporting floor.

When exposed to the bearing plate cover 3 active vertical and horizontal forces supporting the floor sags and this forms a Cup deflection radius of tens of kilometers and has a value in the range 1-4 see this bowl of deflections turns of thin-walled elements in the vertical plane of the outer part in the direction opposite to the direction of the resultant active force. When turning thin-walled elements in their lower part is moved to a higher level than the upper, thereby redistributing a vertical force in a horizontal plane.

As thin-walled components made convexo-concave in longitudinal and transverse directions and are arranged at an angle to a vertical plane and inclined in the transverse direction of the side surface diverging slope from bottom to top, then when the load is engaged in work not only weakened the soil located around items, and masses more durable deep layers of the soil located below the thin is more durable deep layers of the soil are involved thin-walled elements of the base. At the same time creates maximum horizontal and partly vertical reactive resistance of the soil attached to the supporting floor of the active forces.

The proposed design of the bearing support structure ensures its high bearing capacity and the constancy of the spatial position in static and dynamic state irrespective of the magnitude of the vertical active and reactive forces and heave and horizontal forces (offset from temperature, slope, and others), which gives the possibility to build various structures on weak and permafrost soils and earthquake-prone areas.

SUBSTANCE: method of foundation construction involves installation of embedded posts, capping beam and junction units for posts and capping beam. Preliminary soil excavation is performed at the planned foundation point to form 'trough' with horizontal bottom covered by sand filling. Then posts are embedded by pressing to a definite depth, and horizontal thermal insulation screen is laid on prepared sand filling in horizontal 'trough' bottom plane by putting the screen on embedded posts from above in the holes for posts made in the screen in advance, with further mounting of capping beam onto embedded posts by junction units. Then sleeper wall of basement element is attached to external side of embedded posts, which in turn carries vertical thermal insulation screen linked to horizontal thermal insulation screen, and water-proof key covering embedded horizontal plate of thermal insulation screen from above is placed in 'trough' onto the space formed by two screens, with thermal insulation screen covered by sand cushion and then by flagged path. Horizontal screen is covered by sand cushion at internal post side, while vertical wall of thermal insulation screen attached at external sleeper wall is rigidly connected to embedded posts.

EFFECT: enhanced operational quality, reduced cost of lodging construction.
